Method of use of wet gas flowmeter
There are two types of wet gas flow score: one is, selected, generally used in the corrosion resistant gas range.In addition, the selection of materials, corrosion gas can be accurately measured.The wet gas flowmeter is one of the common instruments in the laboratory.In the precise measurement of the total volume of gas, the accuracy is high, very small total flow, its deviation is small.It can be used immediately to measure the total gas flow accurately, and can also be used as a standard instrument to calibrate other steam flowmeters.
Method of use of wet gas flowmeter
Directions for use
1. Place the instrument on the work center table, adjust the anchor line screw to make the level bubble located in the management center, and keep it in use.
2. Open the sealing screw cap of the water level controller and drag out the inner wool rope.
3, within the thermometer or vacuum gauge socket, is introduced into distilled water, within the instrument to be terminated when distilled water from a water level controller of hole wall is introduced into distilled water, when the unnecessary distilled water from the hole wall along the browse line flow clean water level controller (long time discharge is when a drop flow clean), within the sealing nut will browse line yield level controller, and fastening nut sealing.
4. Install the thermometer and vacuum pressure gauge.(10Pa per cell) >
5, according to the air in and out of the gas azimuth connection, and sealing.
6, open the valve, you can carry out accurate gas measurement.
Common problems
A) during the whole application process, always pay attention to the maintenance of water level line in the instrument, otherwise it will jeopardize the accurate measurement accuracy.
B) in application, the temperature should be maintained between 15 ℃ and 25℃. The average temperature is the same as the indoor temperature, and the temperature difference should be ≤2℃.
C) start reading after several weeks of operation of the meter hand.
D) when the working pressure of the measured gas exceeds the normal working pressure value of 1~6 times (1~6Kpa), the instrument and equipment can still carry out the work. At this time, the vacuum pressure gauge should be taken out and the installation hole of the vacuum pressure gauge should be plugged with a rubber plug without holes.
E) when the total flow rate of the measured gas exceeds the rated total flow rate and is applied within the range of the excess total flow rate, the instrument and equipment can still carry out the work, but the precision of the accurate measurement will be reduced to some extent.
F) when the meter is not used for a long time, the distilled water in the meter should be put neatly. When discharging, the drainage valve should be applied first, then the head of the meter should be lowered, and then the outflow bronchi should be lowered, so that the water in the drum wheel can be put clean after several times.
G) the meter is not suitable for installation in a low-temperature room to prevent internal freezing.
H) under normal application conditions, the accuracy shall be tested at least once a year.
Porcelain city Shanghai instruments co., LTD., founded in 2011, founded by former Siemens engineers MrStone, specializing in high quality, high precision, high frequency, high temperature, high pressure, wide range of flow meter research and development production, production strictly enforce the ISO9001 standards, the use of independent research and development of technology, substitute the gaps in China's small flow meter, the product can completely replace the Max, KRACHT (clark), OVAL and other international brands.
